I recently had a horrible cough and felt a cold coming on and taking one of these twice a day (along with my regular vitamin C and Zyflammend)seemed to ward it off.
However, it is really hard for me to swallow these - I feel the curcumin taste the moment it's in my mouth, making me gag even before I start swallowing it. I found the only way I could somehow down it was with a chocolate shake. It also gives me curcuminy burps.
